ECM swap

Hallo to everybody !!!
My next mod is ECM swap ( old 870 out, new 165 in ). My question is : Can I use 2 standard europeen relays ( see pic ) or must I take the original ones ( hard to find in Germany ).
Thanks,
Uwe

You can use the locally available relays. May need to splice in different connectors and double check the current ratings. But a relay other then the GM ones will work.

I've used alot of Bosch relays with GM stuff.
If you're going with a non automotive series of relay you want to check the field winding resistance.
